John; IPX is very sensitive to delay variation. That is why you are dropping IPX more than IP. My Novel expert recommends running an NWIP tunnel if you have a novel server on each side. I know. Great. Another tunnel. The large number of differed packets could mean several things. My first

Sean. There is nothing wrong with your BGP configs. Everything is working just the way you told it to. :) What is wrong is your test methology. Since 192.168.1.0 is unknown in As200, you must do an extended ping on router 1 to router 3 with the loopback address as the source of the ping. HTH

Nul0 has several applications. Security is a good one. Your point that martian routes can appear in the route table rather than exception processes is also a good point. It also is a good way to prevent routing loops on summary addresses, for example. Regards Doug Message Posted at:

Dwayne; The short answer is no. If static routes sufice for your current IGP, they will work for BGP as well. The key is not to rely on BGP to provide reachability within your AS. (network). I would strongly concider creating loopback addresses if you have multiple paths in your network. this

You are missing a default route to the internet. ip route 0.0.0.0 0.0.0.0 206.107.237.x where x is the address of the cable modem. However if the 2521 can't see it, either somthing else is wrong. Are the interfaces Up,Up? A sh ip int bri should tell the tale on the 2501. HTH Doug Message

If you were running RIP V1 on your network, correct design would dictate that all the local networks must appear in the routing table of your routers. If one of your users accesses a network not in the table, the router would send an icmp network unreachable with no IP classless and an icmp

Tom; I think a discussion on this will be interesting. My perseption is that a classful/classless router has nothing to do with VLSM or CIDR. The only issue is how it handles the default route on networks that are attached to the router with at least one interface. Classless - attached net,

Bruce; Your Idea is as good as any. The idea is to drop back to your CIR in times of congestion to avoid dropping frames (and incurring re-transmits) however, with 0 cir, there is no logical point to set it. Set it lower and hope you drop less frames. Personally, on a zero cir net, I would bag

Just a thought. Are you really running rip V1 or are you running Rip V2 in compatibly mode. The first config would look like: Router Rip Net 172.10.0.0 The second would look like: Router rip version 1 net 172.10.0.0 Just a thought. Doug Message Posted at:

In your example, both RC and RE need to run both L1 and L2 processes. Doyle would refer to them as L1/L2 routers. So your second line would read: L1 L1 L1/L2 L2 L1/L2 L1 L1 Since RD only connects to other routers that run L1/L2 SPF, it can choose to be either L1 only, L2 only or both. RC and

The Short answer is it can't be done. You can have a Fractional T-1 with 56K or 64K, but all 24 channels are ALWAYS there, you have just chosen to ignore some. DDS 56K is different and not interoperable. in order to interoperate, you need a channel bank to connect the 56K and T-1 (one channel}
